PATENT WILLIAM SKAKEL, OF WAGNER, SOUTH DAKOTA.

CULTlVATOR-SHOVEL CLEANER.

SPECIFICATION forming part of Letters Patent No. 667,741, dated February 12, 1901.

Original application filed March 12, 1900, Serial No. 8,308. Divided and this application filed June 27,1900. Serial No. 21,727;

To (0Z5 whom it may concern:

Be it known that Ll/VILLIAM SKAKEL,a citizen of the United States, residing at Wagner, in the county of Charles Mix and State of South Dakota, haveinvented certain new and useful Improvements in Cultivator-Shovel Cleaners, of which the following is a specification, the same being a division of my application, Serial No. 8,308, filed March 12, 1900.

It is well known that in the use of cultivators in clayey, damp, or sticky soil it is exceedingly difficult to keep the shovels scoured or cleaned, and unless the shovels are maintained in a scoured and clean condition the operation of cultivating is rendered difficult and troublesome. It is the general practice in the use of cultivator-s to raise the plows from the ground when the soil has become stuck thereto and clean the shovels by hand and any means obtainable.

The object of this invention is to construct and apply a shovel-cleaner attachment to a cultivator which will be automatically operated by the travel of the machine whether the shovels are in or out of the ground, the attachment also being of a nature 'to permit the cleaners to be operated by hand, if required; and the invention consists in the features of construction and the combination of parts hereinafter described and claimed.

In the drawings only so much of a cultivator as is necessary to show the invention is illustrated, the parts not fully illustrated being of the formation of the parts in my said application Serial No.8,808 or of other form of construction for the parts.

In the drawings, Figure l is a side elevation with one of the carrying-wheels removed to show the driving-Wheel and chain for operating the shovel-cleaners. Fig. 2 is adetail, being a rear elevation of the end of a cultivator having thereon the driving connection for operating the shovel-cleaners; Fig. 3, a detail in elevation of the shaft and cam for operating the shovel-cleaners; Fig. 4:, a side elevation of the parts shown in Fig. 3; Fig. 5, a perspective view of one end of the cam of the shovel-cleaning device; Fig. 6, a detail in plan of one forward corner of the frame, showing the swing-board for the forward end of the plow-beams and the lever and rock-shaft for the shovel-cleaners; Fig. 7, a detailofthe joint and swing-board and connection for the KNo model.)

plow-beams and the rock-shaft and its arm for the shovel-cleaner; Fig. 8, a detail, being a side elevation of one of the plow-beams, showing the shovel-cleaner and the devices for operating-the same; Fig. 9, aperspective View of a shovel and a cleaner; Fig. 10, aperspective View of the bracket or support carrying the L-lever of the shovel-cleaning device, and Fig. '11 a perspective view of the L-lever of the shovel-cleaner.

The machine is to have carrying-Wheels A at each end of an arched axle B, which wheels are mounted on spindles a, extending out from the arched axle and entering the hubs a of the wheels. A frame 0, preferably of steel or iron,of angular shape in cross-section, is attached to supports 1) on the axle B and held in place by clips Z) or otherwise, and a truss-rod B for the axle can be used, if desired.

The machine is to be provided with p1owbeams, which may be of the split-beam variety, having a main beam D and a secondary beam D, both the main. beam and the secondary beam carrying at their rear end a shovel. The beams can be arranged so as to have two beams carrying four shovels, as usual, or they can be arranged with three beams, the center one carrying three shovels, as in my application of which this is a division. The forward end of each-plow-beam may be attached by a two-Way coupling E, which permits of a lateral swing, and by its attachment to a carrying-board E vertical swing is permitted. The coupling E for the lateral swing, as shown, consists of a plate or casting 9, pi voted at its forward end between ears on a bracket or casting e by a bolt 6 with the bracket or casting 6 attached to the swing-board E, which board extends across the front of the machine.

A rock-shaft F is mounted in suitable bearings on the tongue or frame of the machine, so as to extend laterally across the machine. This rock-shaft is provided with an arm ffor each plow-beam, and a chain f connects the plow-beam with the arm f, so as to give the necessary flexibility for the movements of the beam. A lifting and setting lever F is pivotally mounted on a standard F which standard at its upper end has a rack F for cooperation with a pawl or catch on the lever F for the lever to raise and lower the plowbeams and be locked and held in its adjusted position. The lever F, as shown, has a rearwardly-extending arm f and a chain f connects this arm with an arm on the rock-shaft for the downward movement of the lever to partially rotate the rock-shaft and raise the plow-beams simultaneously. A cross-bar G is shown for connecting the plow-beams together and has its movements controlled by levers G, two being provided in order to permit either hand of the operator to be used in moving the beams, one to grasp and move the levers, leaving the other hand free for driving or other purposes. The levers G also enable the plow-beams to be raised vertically, when desired for any purpose, and, as shown, each plow-beam is connected with the crossbar by a pendant or hanger g and a brace 9, but can be otherwise connected, so long as the connection is one permitting the plow-beams to have a support by which they can be moved in unison by the movement of the cross-bar.

The parts so far described relate to the subject-matter of my said application Serial No. 8,308 and are fullyset forth and their-operation described in said application, and therefore the construction and operation of these parts in detail are not herein described and pointed out, as the parts form no part of the present invention, which relates to the shovel-cleaners, which will now be described.

One of the carrying-wheels A has secured to its hub a in any suitable manner so as to revolve therewith a sprocketwheel H, and a sprocketchain It runs over this sprocketwheel and over a sprocket-pinion I, so that with the revolving of the carrying-wheel A the sprocket-chain will be driven to rotate the sprocket-pinion I. This pinion is on the end of a shaft J, mounted in bearingsj on a support J, attached to the frame-piece C, and, as shown, the pinion is attached to the end of the shaft by its hub 11 and a suitable set-screw, and between the hub and the bearings for the shaft is a collar or thimble 01; but the thilnble or collar could be omitted and the hub t' extended, if so desired, in order to properly locate the pinion in line with the sprocket-wheel on the carrying-wheel. The shaft J at its opposite end carries a cam K, which cam has an acting face It and at its outer corner has an inclined face 7c, projecting beyond the side face of the cam. The acting face 75 when the cam is revolved engages an antifriction-roller Z on an arm or lever L, extended out from a rock-shaft M, such engagement occurring only when the arm or lever and its roller are in the line of the path of travel of the cam and its acting face It. The rock-shaft M is supported at one end in a support 0 and extends transversely across the machine, so as to cover the space.

occupied by the plow-beams, and its other end may be supported on the frame or otherwise. The shaft M, at points in line with each plow-beam, has an arm on, and the limit of throw or rock of the shaft in a forward direction is controlled by a catch or stop on, attached to the swinging board E, as shown in Figs. 6 and 7. The shaft M, in addition to its rocking move ment,has an end wise movement, which movement is limited by pins m on each side of the support 0, as shown in Fig. 6. This endwise movement is for the purpose of enabling the shaft, with its arms, to be moved endwise a distance required to bring the arm or lever L and its roller Z into the path of travel of the cam K and its face 70, so that with the downward movement of the cam through the engagement with the roller the arm or lever moves the arms m forward for a purpose hereinafter explained.

The rock-shaft is returned to its normal position and out of the line of engagement of the cam with the arm or lever by the incline it on the cam, which strikes the end of the arm or lever and through its inclined face moves the rock-shaft end wise out of position, so that on the succeeding revolution of the cam no engagement will take place between the cam and the arm or lever, and no movement of the rock-shaft will occur. The rockshaft is moved endwise, so as to bring the arm or lever Lin proper position for engagement by means of a cord M in the arrangement shown, which cord at one end can be attached to the rock-shaft and extended back and attached to one of the levers G or otherwise, so as to be within reach of the operator for the operator by grasping and pulling on the cord to slide the rockshaft endwise into operative position, which movement should be made when the shovels need cleaning.

A rod N is attached toeach arm on and extends rearward ly and at its rear end has join ted thereto at a two rods N and N and a rod N and its companion rods N and N are to be provided "for each pair of shovels. Each rod N and N is attached to an L-lever O, the attachment being to the arm .0 of such lever, which arm, as shown, is provided with a se ries of holes for the attachment of the rod on one side and the proper attachment of a return-spring 0 on the other side. Each lever O has an arm 0 and an arm 0' and is pi-votally mounted on each beam by means of a support or bracket 0 the same bolt which attaches the support or bracket also furnishing the pivot for the lever. The plate or bracket has a depending car 0 between which and the arm 0 of the lever is the coil spring 0 having the requisite tension to return the lever after each operation from the rock-shaft, such return of the lever 0 also, through the connecting-rods, returning the rock-shaft. A lever O is provided for each shovel, and each lever, at the outer end of its arm 0, has depending therefroin a spring or flexing support P, which support at its upper end is pivotally mounted in an eye or socket p on the rear end of the lever-arm o and at its lower end carries a scraper p to engage the acting face of the shovel Q. Each shovel Q, is car ried by a shovel-block (1', attached to a support g, which in turn is connected with the end of the shovel-beam by a bolt d and a break-pin cl in the usual manner. The downward rock of the shaft M, through the forward movement of the arm m, moves each rod N forward, carrying with it the connectingrods N and N and each of these rods operates its own lever O, producing a downward throw of the outer end of the arm 0, which forces down the spring or flexing support P and moves the cleaner 1) downward over the face of the shovel.

The movement of the cleaners, as before stated, is controlled by the operator through the cord M, and when it is desired to clean the shovels the operator by pulling on the cord moves the rock-shaft M end wise into position for the engagement of the arm or lever L with the cam K, which engagement, as already described, carries down the scraper or cleaner for each shovel, so that all the shovels will be cleaned or operated upon at one and the same time,and when the cleaner or scraper has traveled the full length of its shovel the cam, through its incline It, moves the rockshaft endwise and out of line of engagement of the lever L, permitting the springs 0 to operate and return the L-levers O and the scrapers or cleaners of the shovels and the other parts to normal position. The cleaning operation can be performed with the shovels in the ground or it can be performed with the shovels out of the ground, as may be desired, and such cleaning operation is had through the travel of the machine by the rotation of the carrying-wheels, which rotates the sprocket-wheel, by which arrangement the cleaning operation is automatically performed by the travel of the cultivator, except as to the requirement of moving the rockshaft endwise in the arrangement which, as shown, is performed by hand. It is evident that by disconnecting the draw-rods for operating the levers O the lever would be free to permit the scraper to be passed over the face of the shovel by hand, if so desired.

As shown, each shovel Q is provided with an ordinary shield Q, carried by a bar Q from the plow-beam, as usual, and a tongue R, suitable for the attachment of horses and fastened to the frame of the machine, is to be provided, which tongue being of the usual construction and attached in the usual way is not therefore specifically shown nor described inthis application.
